What Is BiTurbo in Mercedes-Benz AMG Cars

in Nov 6, 2025

When you hear the word BiTurbo on a Mercedes-Benz AMG, you immediately think of power, speed, and high-performance engineering. Mercedes uses the BiTurbo technology to deliver instant acceleration, reduced turbo lag, and a smoother power delivery that makes AMG cars unique and extremely powerful.

In this article, we explain what BiTurbo means, the difference between BiTurbo and twin-turbo, which Mercedes models use it, and which engine types come with this system.

✅ What Does BiTurbo Mean?

BiTurbo means the engine uses two turbochargers to compress air into the engine, increasing horsepower and torque.
In simple words: more air + more fuel = more power.

In Mercedes-AMG models, BiTurbo technology is engineered to deliver:

  • Faster throttle response
  • Higher top speed
  • Better acceleration
  • More efficient combustion
  • A powerful AMG sound

✅ BiTurbo vs. Twin-Turbo — What’s the Difference?

Many people think BiTurbo and twin-turbo are different, but in truth:

✅ BiTurbo = Twin Turbo

Both terms mean two turbochargers.
However, Mercedes likes to use the name BiTurbo as a branding term, especially for AMG engines.

Why Mercedes Uses the Name “BiTurbo”?

  • It’s part of AMG identity
  • It represents precision engineering
  • It differentiates Mercedes performance engines from other brands

So the technology is the same as twin-turbo, but the name BiTurbo is specially used by Mercedes.

✅ Which Mercedes-Benz Models Have BiTurbo Engines?

BiTurbo technology is used in many AMG performance models, including:

AMG V8 BiTurbo Models

These cars usually have the legendary 4.0L V8 BiTurbo or older 5.5L V8 BiTurbo engines.

AMG V6 BiTurbo Models

These models use the 3.0L V6 BiTurbo engine.

AMG Inline-4 (4-cylinder) BiTurbo

Some new AMG four-cylinder engines also use turbocharging, including:

  • AMG A45 / A45 S
  • AMG CLA 45 / CLA 45 S
  • AMG GLA 45 / GLB 45

These engines use a more advanced design, sometimes with one larger turbo, not two.
But the main classic “BiTurbo” badge is mostly used on V6 and V8 engines.

AMG V12 BiTurbo

The legendary 6.0L V12 BiTurbo engine was used in:

  • Mercedes-AMG S65
  • Mercedes-AMG SL65
  • Mercedes-Benz G65 AMG

These models are extremely rare and iconic.

✅ Is BiTurbo Technology Only for Mercedes?

No — BiTurbo is not exclusive to Mercedes, but Mercedes made the term famous and part of AMG branding.

Other brands like BMW, Audi, Porsche, and Nissan also have twin-turbo engines.
However, Mercedes-AMG tuning and calibration gives their BiTurbo engines:

  • Sharper throttle response
  • Stronger low-end torque
  • A unique exhaust sound
  • The feeling of instant power

This great combination is what makes AMG BiTurbo cars special.

✅ Conclusion

Mercedes-Benz AMG’s BiTurbo system is a high-performance twin-turbo technology designed to deliver:

  • Extreme power
  • Instant acceleration
  • Smooth driving
  • Better efficiency

Many AMG models — from V6 to V8, and even the legendary V12 — come with BiTurbo engines. While the technology exists in other brands, the BiTurbo badge has become a signature of Mercedes-AMG performance.
